But I can tell you that it didn't have PAE enabled nor did it have 4G of memory (it either had 1G or 2G, but definately not 4G). Congrats on the cleanup of old tickets, but I can't do any testing for you as I don't have any other machines that did this. The server in question was a busy core router. My current core routers use em and bge chipsets.
